Moron su nsnrotnmvnn,

This invention relates to certain new and useful improvements in motor street'cleaners.

The primary object of the-invention is the provision of a motor driven device adapted for cleaning streets during the passage of the devicethereover, the arrangement being such as to sweep and transfer the sweeping-s to a dumping receptacle, the latter being adapted to be emptied when filled during I the continued operation of the sweeper.

A further ohyect of the invention is the provision of a street cleaner in which the forward driving of the device effects a collection of sweepings under the control of the operator, the sweepings being readily dumped when desired. without dislocating any of the operative connections.

in the drawings forming a port of this 'application and in which like designating characters refer to corresponding parts throughout the several views,

Figure 1 is a side elevation of the device partially broken away.

Fig. 2 is a top plan view thereof.

Figs. 3 end 4: are vertical sectional views taken upon lines Ill-fill and IV lV respectively of Fig. l.

Fig. 5 is a horizontal detail section al View through the forward portion of the device and Fig. 6 is an enlarged elevational fragmentary detail view, partly in section, of the forward portion of the device.

Referring more in detail to'the drawings, a vehicle is provided having a platform 10, rear traction wheels 11, forwardsteering traction wheels'lQ and a hood 13 adapted for covering a driving motor for the vehicle while a drivers seat 14 is arranged upon the platform adjacent the steering wheel 15 A rotor crush or sweeper 13 is trunnioned in forwardly projecting arms 17 pivotally carried by brackets 18 at the forward corners of the platform 10, the said arms having rearwardly arranged substantially semicircjilar toothed racks 18'. A transsheft 19 is yonrnaled in brackets 20 Specification of Letters Patent. Application filed August 6, 1917. Serial No. 134,646.

,for dumping the box 28. iratchet mechanism 38 is carried by the post Eatented Aug. is, leis.

carried by the platform 10 and pinions 2 secured on said shaft are in constant mesh with the racks 18 while a sprocket chain 22 cured on the shaft 19 and a stub-shaft 25 respectively whereby a turning of a wheel 26 carried by said stub-shaft will elevate or lower the arms 17 and the brush it as desired. A spring-pressed latch 93'? is provided for the stub-shaft 25 for maintaining the brush 16 in its adjusted elevated positions. y

A box 28, provided to receive the sweepings, is pivoted within a frame- 29 carried by the platform 10 substantially over the rear axle 30 of the vehicle. An arm 31 forwardly projecting from the'box is grasped. by a U shaped spring clamp 32 when the box is in its normal horizontal position. An arcuate rack 33 projects forwardly and downwardly from the box 28 and meshes with a gear 34:

carried by the stub-shaft 35 journaled in a post 36 and on. which is mounted an operating crank 37 by means of which the rack 33 may be elevated and lowered as desired The pawl and 36for preventing the upward movement of the rack 33 and the tilting of the box until the pawl is released.

Screened ventilating openings 39 may be arranged in the sides of the box 28 if desired. A swingingrear door s0 is provided for the box, the door being hinged at the top thereof as at 41, while a retaining bar l2 which is journaled upon the outer side of the door 4:0 has projecting ends 43 adapted to be sprung over resilient catches 44 carried by the opposite sides of the box 28. A shaft 45 is journaled transversely be neath the platform 10 and is adapted to be driven from the rear axle 30 by means of sprocket chains 46 while a "pulley 47 upon the shaft s5 is adapted to operate a circulating fan 43, a belt s9 being arranged between the pulley 47 and a pulley 50 upon the fan shaft 51. The brush 16 is arranged with n. driving pulley 52 opera-tively ,con-- passes over sprocket wheels 23 and 24: solto the boX 28 by ineansof a telescoping pipe connection 59 having a hinged eonneetioi'i tit) with the outlet 58 aml a swiveleil con nection 431 with the box 2h.

2'. in combination with a vehicle having a platform, a tan and a tyiltably mounted dumping collection box upon the platform, telescopic pipe connections between the box and the tan having SWlYOlttl connection with the box aml hinged connection with the hin a sweeping brush operatively associated with the inlet of the tan, and meansv to!" operating the, fan and the brush.

in testimony whereof I atli l 'ny SlgllilttllG.
